Ukrainian monitoring Telegram channels Exilenova+ and Supernova+ reported the attack on AO Novokuibyshevsk Oil Refinery. Astra, an OSINT analyst, confirmed the fire at the facility and geolocated photos and video filmed by witnesses.
Footage circulated online shows several columns of smoke rising above the plant. Residents of Novokuibyshevsk complained that no air-raid alert was sounded, Astra noted. According to them, a notification from Samara region Governor Vyacheslav Fedorishchev appeared almost two hours after the attack began.
The refinery is part of Rosneft's Samara group of enterprises. The company's website lists its capacity at about 8.8 million tonnes of oil a year. The plant produces more than 20–30 types of petroleum products, including jet fuel used for military purposes.
Ukrainian forces have attacked the plant before. In April 2026, Astra writes, both of its primary crude distillation units, AVT-11 and AVT-9, were shut down. Regional authorities have not yet commented on the consequences of the latest attack.
